An Iraqi court on Sunday sentenced three French citizens to death after they were found guilty of joining ISIS, a court official said.
Captured in Syria by a US-backed force fighting the extremists, they are the first French ISIS members to receive death sentences in Iraq, where they were transferred for trial.
Named as Kevin Gonot, Leonard Lopez and Salim Machou, they have 30 days to appeal.
Iraq has taken custody of thousands of extremists repatriated in recent months from neighboring Syria, where they were caught by the US-backed Syrian Democratic Forces during the battle to destroy the ISIS “caliphate”.
Iraqi courts have placed on trial hundreds of foreigners, condemning many to life in prison and others to death, although no foreign ISIS members have yet been executed.
Those sentenced on Sunday were among 12 French citizens who were caught in Syria and transferred to Iraqi custody in February.
Rights groups including Human Rights Watch have criticized Iraq's anti-terror trials, which they say often rely on circumstantial evidence or confessions obtained under torture.
The country remains in the top five “executioner” nations in the world, according to an Amnesty International report in April.
Analysts have also warned that prisons in Iraq have in the past acted as “academies” for future extremists, including ISIS leader Abu Bakr al-Baghdadi.
